.To all whom may concern-r tain new and useful liwrovem-cnis inilppiirains for Drying lviacai mi and other Edible Pastes, of Wnich the following is a specifloat-ion.

The prunary ob ect oi this havenon is-io provide anappuraius whereby niac Joni and similar food products may be dried Without bending or splitting the goods and Within a shorter space 0" time than is possible under ordinary, atmospheric cond tions, The various other objecis of the invention will be more fully set forth in .thc following descrip'iion of apparatus embodying the invention, which consists in the new and novel features of construcltion and combination of parts hereinafier set forth and claimed;

in the accompan" no" drawinq:

Figure 1 is a vicu in plan my improved apparatus.

Fig. 2 is a central, vertical sect-ion of my improved apparatus showing the same adapted for drying macaroni on sticks or supports as it comes from the press.

Fig. 3 represcnisa sectional view ciimy improved apparatus adapted for drying edible paste in the form of short cutor similar products.

Fig. 4-. is a vertical, sectional View of my improved apparatus showing the same ar ranged on its side as to provide drying compartments arranged one above the oiher. v Referring to the accompanyin' crawings, the apparatus comprises a preierahiyrectangular casing 1 provided with a suitable door 2 at one end, and with air inlets arranged in the side thereof preferably in the top. Said inlets are controlled by dampers l, which may be regulated in any desired manner by a spring 5 or a Weight 8.

At one end of the compartment formed in the interior of the casing is arranged a reversible rotary fan or blower 7, which is mounted on a. shaft- 8 having hearings in brackets 9 supported by the casing. A plurality of heating pipes 10 are arranged ad jacent to the fan.

The goods are arranged in the central part of the casing and znay be mounted upon the sticks upon which goods, such as macaroni, are subjecied'to a preliminary drying. These sticks may be supported upon lodges or ])1'O}CUOI1S 11 secured to thecasuig. if des red, however, the goods may.

be mounted by means of the sticks upon acarriage or rack 12 adapiedlo be run into she casing upon a suitable track l i pro y'ided therein; In case the goods comprises edible paste, such as sea shell or short cut,

hO'WGYQT, these goods are preferablyplaced in irays which are carried upon suitable racks.

iii-case the goods are put into the casing and supported therein upon the ledges 11, partition 15 is preferably provided in the casing, which may be deiachably secured in place by means of suitable angle-irons 16, or in any other desired manner, permitting the some to be removed Whenever desired. a bafiie plate or screen 17 is also preferably arranged between the an and the goods in such a manner as to better-control the circulation of the air on the goods.

iii {no end or" lzhe'casing opposite the fan,

a valve 18 is nivotaily mounted so that the I general direction of ihe air current, as Well as its velocity, may be controlled. Said valve is preferably pivoted in line with guide plates 19, which tend to distribute the air currents-through the open space at the end of the casing opposite the fan. Said valve is so arranged and proportioned that all of said space may be closed and the air forced to circulate directly through the goods if desired. This arrangement is pref crably' employed when the goods are mount. ed on the movable racks, as shown in, Figs. 3 to 2 inclusive.

Ii desired, the casing may be arranged so that two air circulating or drying passages may be arranged one above the other, as shown in Fig. 4-. In this case, the upper portion may be used for drying goods on sticks and the lower portion may be used to receive a movable rack, although it is obvious that goods may be placed in only one of the sections if desired.

in operation, the fan is caused to revolve by the pulleys 20 at the causes the air to circulate through and around Hie goods. in case the partition is used. the valve is arranged in its open p0- sidon and the air is caused to pass upward lzhrough the goods on one side of the parti tion, thence throug the space at the opposite end of the casing, and then downward desired speed, which to the other. 1 until thedrying is completed. During this through the goods on the other side of the partit on; to the fan. In case the partition is removed, however, and the goods are'inounted'on movable racks, the valve is placed in its closed position as shown in Fig. 3, thus comple'tely'closing the passage at this end of thejcasing,

I and'causing the air to pass through the goods from one side of the rack This operation is continued a screen between the fan compartment and the dry ing compartment, a fan in the fan com- 'partment arranged centrally thereof and facing'one of the Walls of said compartment, a valve controlled air passage at the end'of the'drying compartment opposite the 'fan compartment, a valve centrally located in said passage and valve controlled air inlets communicating with said passage.

2. An apparatus for drying macaroni and other edible pastes comprisinga drying compartment and a fan compartment, a trans- I verse partition in the fan compartment, 2,

rotary fan in said partition for'moving the air in the heating compartment to and from the drying compartment, a removable partition lengthwise of the drying compartment, a valve controlled air passage between said partition and the wall of the casing, and valve controlled inlets communicating with said passage. 7 I

3. An apparatus for drying macaroni and other edible pastes comprising a drying compartment and a fan chamber, a battle screen between the drying compartment and the fan chamber, a partition in the an chamber perpendicular to said battle screen, a rotary fan in said partition arranged to ischar e the current of air parallel to the ba e screen, a baffle plate in said fan compartment adapted to intercept a portion of said air and reflect same through the screen into the drying compartment, to produce a circulation of air in the drying compartment. 4. An apparatus for drying macaroni and other edible pastes comprising a casing, a

fan arranged at or near one .end of saidoasing for produeing a current of air therein, apartition iitsaid casing, a valve;ar ranged adjacent the end of the casing op-v posite said fan, means-for heating the air in said casing, and means for regulating the humidity of the air in said casing, substantially as described. 1 This specification signed and witnessed this 23rd day of November, A.
